Multi-layered ceramic capacitor

Abstract

A multi-layered ceramic capacitor (MLCC) includes: a multi-layered capacitor main body formed by stacking a plurality of dielectric layers and having a size of 0.9 mm in width and 0.6 mm in length; two inner electrodes formed on each of the plurality of dielectric layers, an inner interval therebetween being 70 μm or smaller and an outer interval between the inner electrode and an edge of the dielectric layer being 60 μm or smaller; and a plurality of outer electrodes formed on an outer surface of the capacitor main body and electrically connected to the inner electrodes.
